Justin Bieber wasn't the only one making the girls scream outside NYC's Madison Avenue Dolce & Gabbana boutique — we also witnessed a couple excited fans lose it as they saw Anna Wintour walk in! Anna and Justin joined Brooklyn Decker, Chace Crawford, and Usher yesterday for the brand's Fashion's Night Out bash. The evening had a "passionate duo" theme in celebration of their new lipstick line, and platonic and romantic couples were there aplenty. Justin had his manager, Scooter Braun, on hand while Jeff Gordon had wife Ingrid Vandebosch, Gossip Girl's Kelly Rutherford and Matthew Settle stuck together, and Leann Rimes showed PDA with Eddie Cibrian. Justin stuck around to sign the purchases of a few lucky fans, but later wrote on Twitter, "That place was a zoo!" Justin also shared a photo of himself, Scooter, and Usher, dubbing them the "three musketeers."
